'l'.'he invention relates generally to the construction of screens for. casement windows, and more particularly to screen construction adapted to be detachably mounted on standard metal casetion. which construction is simple and economical to manufacture, easy to install and remove, and which presents a neat and pleasing appearance when installed.

. I n general terms. the present construction in- The sash frame i8 may be of similar construction, having the outer flange |9 for overlapping the outer flange 20 of the casement frame, and

being adapted to swing to the outside of the ally at 23 is adapted to fit on the inner or rooml side of the casement frame, within the usual inside trim and stool members 24 and 25, respectively, of the window frame. 'I'he screen frame 23 is preferably of all metal construction. having the channel portions 26 in which the screening 21 is secured, and an inturned ange 28 extending continuously around the four sides of the screen frame.

'Ille screening 21 may be tightly held or clamped in the channel portions 26 by means of retaining rods 29, in a usual manner; and the inner edge of the flange 28 is adapted to abut the room side of flange 22 of the casement frame Il.

The improved means for detachably mounting the screen frame 23 on the casement frame preferably includes clips 30. As best sl'own in Figs. 7 and 8, each clip has a resilient U-shaped portion 3| (inverted as viewed in Figs. 7 and 8) adapted to be snapped on the inner ange 22 of the casement frame, in the manner indicated in Figs. 2, 4, 9 and 10.

At one side of the U-shaped portion 3| of each clip is formed a box like portion 32 having a slot cut in the upper side thereof to form a socket 33, and the clips are positioned on the ange 22 of the casement frame so that the portion 32 is at the room side of said flange, as indicated in the drawings.

The improved clips 36 are snapped on opposite sides of the casement frame when the window is open, preferably one clip at the center of the head member |2, and two clips at positions spaced longitudinally on the sill member I6, as shown in Figs. 1 and -3; and the sockets 33 of opposite clips open toward each other.

'I'he improved means on the screen frame 23 for detachably locking it to the clips 36 for mounting the screen frame on the casement frame, preferably includes a latch 35 in the upper portion of the screen frame and adapted for engaging in the socket 33 of the clip 30 mounted on the head member I2 of the casement frame.

The bottom portion of the screen frame 23 preferably has adjustable projections indicated at 36 for entering the sockets 33 of the clips 30 which are mounted on the sill member I6 of the casement frame.

'I'he latch 35 may be a single piece of metal extending through the slot 31 in the upper channel portion 26 of the screen frame, and the latch 35 is provided with an angular finger piece 38 at its room side end, and with a hook 39 at its other end. The continuous flange 28 is notched out at its inner edge portion as at 40, to permit the hook 39 to pass upward therethrough.

Preferably, a positioning plate 4| is secured to the flange 28 above the latch 35, and the plate 4| is provided with a rectangular notch' 42, opening at the inner edge of the flange 28, said rectangular notch being adapted to t around the box like portion 32 of the clip 30 when the screen frame is mounted on the casement frame.

The notch 40 in flange 28 registers with notch 42 in plate 4| and when the notch 42 is positioned around the box like portion of clip 30.

the socket 33 of the clip registers with notch 40, so that the hook 39 of the latch may' engage in said socket and lock the screen frame against the casement frame.

'Ihe finger piece 38 of the latch may be en- 5 larged at its entrance to the slot 3.1 in the screen frame to provide stop shoulders 44, and a strengthening plate 45 may be secured on the channel portion 26 around the slot 31 for abutting said shoulders to limit releasing movement l0 of the latch.

A spring 46 may be interposed between the latch 39 and the bottom of the channel portion 26 for urging the latch toward the closed position shown in Fig. 2. l5

The adjustable projections 36 for entering the sockets 33 of the clips 30 mounted on the sill member I6 of the casement frame, may be studs or bolts projecting through the flange 28 at the bottom of the screen frame. The heads of the 20 bolts 36 are adapted to enter the sockets 33 for holding the bottom of the screen frame in place against the casement frame. Each bolt 36 is threaded through a plate 48 secured on the inside of flange 28, and a lock nut 49 is screwed 26 on the inner end of the bolt, so that the length thereof which projects below flange 28 may be adjusted to meet variations in the screen frame and casement frame.

In installing the improved casement window 30 screen on a standard type of casement window, the three clips 30 are first snapped on the inner flange 22 o1' the casement frame, with the fingers, the sash frame |8 being swung open; one clip being positioned at the central portion lat- 35 erally of the head member, and two clips being spaced on the sill member substantially as shown in Fig. l. The screen framemay then be positioned against the room side of the casement frame by entering the heads of bolts 36 in the n sockets 33 of the lower clips 30, in the manner shown in Fig. 4, after i'lrst sliding the clips along the flange 22, if necessary in order to have the sockets register with the bolts 36.

After the heads of bolts 36 are entered in the y sockets 33 of the lower clips 30 the operator grasps the finger piece 38 of latch 35 and lifts upwardly thereon to lower the hook 39 thereof, as shown in Fig. 4. The upper portion of the screen frame may then be moved into position 50 with the inner edge of ange 28 abutting the flange 22 of the 'casement frame, and with the notch 42 of the positioning plate 4| tting around the box portion 32 of upper clip 30. The latch 35 is then released, and the spring 46 returns the 55 same to closed position with the hook 39 engaged in the socket 33 of the clip, to lock the screen frame against the flange 22 in screen tight position. Obviously, the upper clip V3|! may be slid e0 along the flange 22 of the head member |2 in order to make the box portion 32 register with the notch 42, if necessary.

In order to remove the screen frame from the window for washing windows, or for the winter g5 season, it is only necessary for the operator to lift the latch 35, and the screen frame may be removed by pulling the top of the same(` outwardly and upwardly to withdraw the heads of bolts 36 from the lower sockets 33. 70

As shown in Fig. 1, where the operating handle 50 for the casement window is located in the center of the height thereof, the screen is provided with a horizontally, sliding panel indicated at 5|. which remains open when the window is 75 may be equally well applied to easement windows closed so that the handle 50 projects through the screening. p l.

As shown in Fig. 3, where the easement window isof the standard type having the operating handle 50 located below the center of the height of the window, the lower part of the screen proper may be constructed as a vertically sliding panel indicated at 52, which is kept open, as shown, when the window is closed to accommodate the handle 50. Otherwise, the construction ofthe improved screen frame and screen frame mounting means is identical with that in Figs. Vl

and 2.

Where the easement window is under frame operated, that is, where the locking handle and operating lever works through the xed case-v ment frame, there is unobstructed space for lapping the improved screen frame all around, and the improved screen may be made in a single panel, full size.

The present improved easement window screen where .the sash are equipped with 'adjusting braces at the sill, by providing a metal cover with a hinged front for the adjusters.

, The 'improved clips provide means for detachably mounting the screen on standard metal cement windows of various types, without requiring the services of a skilled workman, or the drilling, tapping or any other operation on'the easement frame, requiring tools; because the clips may be snapped on with the fingers.

Moreover, the clips do not have to be accurately located on the easement frame before the'screen is applied, because they can be slid on the frame with the fingers, as required when the screen is attached. .l

The improved clips are all alike, and therefore interchangeable, consequently involving a minimum of manufacturing cost, and saving `trouble in installation.

Furthermore, when the screen is removed for the winter season, the clips may be removed easily from the easement frame, without the use of tools, so that the unscreened window presents the same appearance as before the screen was initially installed, because the easement frame has not been disflgured in any way.

The present screen frame and clips are simple and economical to manufacture, and may be installed or rerndved in a few seconds by the most inexperienced person without lthe aid of any tools.

When installed, the improved screen presents a neat and pleasing appearance.

The present improved easement window screens can be installed on easement windows where the easement frame projects such a slight distance from the window frame as to preclude attaching screens of prior constructions, because the improved screen frame requires only 1/4" allaround for overlap on the easement frame, and the sill or frame may be slightly cut or notched to allow the improved clips to be snapped on the easement rame. f
